EV Motor Improvement With Torque-Dense Materials and Advanced Powertrain Technology


Higher power and torque density in advanced electric motors for electric vehicles, along with increased efficiency, are of key importance to improving vehicle performance. One way to realize these goals is by constructing the stator and rotor using high-induction, high-permeability, and low-loss soft magnetic materials. Using such advanced soft magnetic materials provides a given EV design higher acceleration, improved range, higher payload capacity, and increased space savings. Recent advancements in the processing of thin, laminated stator and rotor stacks have been paramount in enabling optimal motor performance. This 60-minute Webinar will examine these advancements and take a detailed look at examples of power-dense and high-efficiency motors that use high-performance, soft magnetic alloys.

Topics include:

  • How using high-induction, high-permeability, and low-loss soft magnetic stator and rotor materials can increase the torque and power density of the motor in combination with improved efficiency Current approach and consequences
  • Various options for realizing the torque and power benefits by about 15-35% using these high-performance material solutions versus present technology
  • How these high-performance motors can result in improved electric vehicle performance such as higher acceleration, improved range, higher payload capacity, and increased space

A Q&A session will follow the technical presentation.
